TELEGRAPH OR-TELEPHONE CALL MECHANISM.

SFECIFICATION forming part of Letters Patent N o. 665, 134, datedJanuary 1, 1901. Application filed March 21, 1900. Serial No. 9,571. \Nomodel.)

To aLZ whom if; may ooncera:

, Be it known that I, EDGAR E. SALISBURY, a citizen of the UnitedStates, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented new Improvements in 'lelegraph or Telephone CallMechanism, of which the following is a full, clear, and exactdescription.

This invention relates to improvements in telegraph and telephone calldevices; and one object is to provide a simple mechanism for releasingthe break-wheel upon an upward movement of the receiver-s11pportingarmand also for locking the said arm in its upper position and releasing itafter the rotation of the break-wheel; and a still further object is toprovide a simple means for winding and releasing the call mechanismwithout removing the receiver or disturbing the supporting- 2o armtherefor.

I will describe a telegraph and telephone call mechanism embodying myinvention and then point out the novel features in the ap-' pendedclaims.

Reference is to be had to the accompanying drawings, forming a partof'this specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is an elevation showing the re- 0 leasing mechanism and thesupporting-arm connections. Fig. 2 shows the device for releasing thebreak-wheel independently of the supporting-arm. Fig. 3 is a viewsimilar to Fig. 1, but showing the parts in a diiferent 5 position; andFig. 4 is a, sectional view.

Referring to the drawings, 1 designates a casing of any suitablematerial and in which is arranged the frame 2, supporting the operatingparts, which comprise the ordinary o spring-motor for rotating thebreak-wheel 3, which coacts with a contact-plate 4, with which one ofthe linewires is connected, while the other line-wire is designed to beconnectedito the call mechanism, which is in electrical connection withthe break-wheel 3, in the usual manner. Oppositely arranged on thebreak-wheel are two outwardly-extended stop-lugs 8 9, designed to beengaged by a lug 10 on a locking-lever l1, pivoted to 5 0 one of theframe-plates, as clearly shown in Fig. 1. This locking-lever is moveddownward to engage with either one of the lugs 8 or 9 that may be withinthe path of the lug 10 by means of a spring 12. The locking-lever 11 hasa curved portion 13, which will engage over the end of the arbor 21, andextended outward from the end of this curved portion is a finger 15 fora purpose to be hereinafter described. A pin 16, attached to the hub 14,is designed to engage with the lockiug-lever 6o 11 to move it out of itsconnection with the pin or lug 8 or 9, when the arm 7 is moved upwardlyby a spring 17, connected at one end to said arm and at the other end toa plate of the frame.

As a means for preventing the arm 7 from being moved downward before thebreakwheel shall have made its necessary rotation I employ a lockingdevice for said arm, here shown as an angle-lever having a hook portion18 adapted to engage with a pin extended inward from the arm. Thislocking device has a downwardly-extended member 19, designed to beengaged by a pin 20, attached to the arbor 21. When the pin 20 isreposing against the member 19, the spring movement would have completedthe break-wheel revolution, and the arm-7 should be in its upwardposition. This engagement of the pin 20 with the lever i9operates todraw the hook 8o portion 18 inward sufficient to relieve the arm 7, sothat when the receiver is replaced on the hook said arm will be drawndown to its normal position by the weight of the receiver. Also attachedto the arbor 21 is a pin 22, designed to engage with the finger 15 whenthe device is to be wound and released without removing the receiverfrom the receiver-supporting arm.

On the innerend of the arbor 21 is a toothed 0 wheel 23, designed to beengaged by a pawl 24, pivotally connected to a lever 25, to which oneend of a spring 26 is attached, the free end of said spring beingsecured to the frame. The pawl 24 is held yieldingly by means of a 5spring 27. a

In operation, assuming that the lug 10 of the locking-lever is inengagement with one of the pins 8 or 9 and the receiver is holding thearm 7 in its downward position, with the arbor 21 wound sufficiently tocause the break-wheel to make one-half revolution,

upon removing the receiver the said arm '7 will be drawn upward by thespring 17, so

that the pin 16 by engaging the lever ll will move the lug out ofengagement with the pin on the break-wheel, thus allowing the breakwheelto be rotated by its spring. After the arm 7 shall have been moved toits uppermost position the hook l8 will swing underneath the pin on saidarm, preventing its downward movement until the break-wheel shall haverotated, and during this movement the arbor 21 also rotates, causing thepin 20 to engage with the part 19 of the locking-lever, moving the hookout of engagement with the pin, so that the arm 7 will be again moveddownward to its normal position with the receiver supported thereon.

Should it be desired to signal without removing the receiver from thesupporting-arm, the lever 25 is to be moved downward, so that the pawl24, engaging with a tooth of the wheel 23, will rotate the arbor,causing the pin 22 to engage with the finger 15, and lifting thelocking-lever 11 out of its locking engagement with the break-Wheel, sothat it may be rotated by the spring action of the spring movement.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a telephone and telegraph callmechanism, a break -wheel, a locking device for said call mechanism andbreak-wheel, a receiver-supporting arm, a hook-lever for locking saidarm in its upper position, means carried by said arm for releasing thebreak-wheellocking lever, and means for releasing said locking-leverwhile the receiver-supporting arm is in its lower position andsupporting the receiver, substantially as specified.

2. In a telegraph and call mechanism, a break-wheel, a locking-lever forsaid call mechanism and break-wheel, a receiver-supporting arm, meanscarried by said arm for releasing the break-wheel-locking lever, alocking device for said arm when in its upward position, said lockingdevice being adapted to hold the arm until after the call mechanism hascompleted its full action, and means for releasing said locking devicefrom the arm after the break-wheel shall have made its proper movement,substantially as specified.

3. A telegraph and telephone call mechanism, comprising a breakwvheel,pins extended from said break-wheel, abreak-wheel-locking lever, havinga lug adapted to engage with either one of said pins, areceiver-snpporting arm, a pin carried by said arm for engaging with thebreak-wheeHocking lever, to release the break-wheel upon an upwardmovement of the arm, a main arbor, a toothed wheel on said main arbor,and a yieldingly-held lever carrying a pawl for engaging with saidtoothed wheel to rotate the main arbor, substantially as specified.

i A telegraph and telephone call mechanism, comprising a break-wheel, areceiversupporting arm, an angle locking-lever having a hook adapted toengage with a pin carried by said supporting-arm, a spring adapted toquickly raise the arm to its locked position upon a removal of thereceiver, and a pin carried by the main arbor for engaging with anextended member of the angle locking-lever to release the supporting-armupon a completion of the break-Wheel movement, as set forth.

5. In a telegraph and telephone call mechanism, a break-wheel, a mainarbor, a locking-lever for the break-wheel, a toothed wheel on the innerend of said main arbor, a spring yielding lever, a stn'ingpressed pawlcarried by said lever and adapted for engaging and operating the toothedwheel, a pin carried by the arbor for releasing the locking-lever fromthe break-wheel, and a receiver-supporting arm mounted to turn on thearbor, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDGAR E. SALISBURY.
